Supply Planning Behavior and Concepts for Process Manufacturing
Let's talk about the business logic employed by Supply Planning when it plans process manufacturing facilities and activities.
In a constrained supply plan, you need to understand some of the behavior and concepts for process manufacturing, such as the following:
-
Supply planning behavior
-
Considerations when you define and plan for process manufacturing
-
Batch quantity concepts
Supply Planning Behavior
The following are some supply planning behaviors for process manufacturing:
-
The supply planning process plans for existing process work orders and recommends new supplies, based on process work definitions.
-
The planning process recommends new supplies in proportion to the output quantities for primary, co-product, and by-product supplies.
-
The batch quantity linearly scales to the primary output quantity and all the output and input items on the work definition.
-
For existing process work orders, the supply planning process considers operation level scrap to determine the remaining planned quantities of output products associated with current and future operations.
-
If an item is the primary output in one work definition and a co-product in another work definition, the work definition in which it's the primary output is used to create a supply for this item to meet demand.
Considerations When You Define and Plan for Process Manufacturing
Consider these points when you define and plan for process manufacturing work definitions in a constrained supply plan.
-
The unique criteria for work definition selection by supply planning is based on primary output item, work definition name, and highest production priority.
-
At any given point in time, an output item can be associated to one and only one operation. The same product can't be completed from multiple operations.
-
A work definition operation can complete more than one output item.
-
Output of one operation can't be the input product at the last operation.
-
It's not mandatory to attach any output product at the last operation.
-
Item shrinkage is supported for process work orders and planned orders.
Batch Quantity Concepts
Using batch quantity while defining a work definition helps you to specify the product outputs, ingredients, and resource usages with a user-friendly range of numbers instead of small fractions or large numbers.
There are some additional batch quantity concepts. Batch quantity:
-
Is the quantity of the production batch used for batch sizing and scaling.
-
Is the quantity that moves between the operations in a work order.
-
Linearly scales to the primary output quantity and all the output and input items in the work definition.
-
Can't add up to the sum of the quantities for the output items, or the sum of the input items, or both.
